Rhabdoid meningiomas may also display some epithelial qualities of the tumor cells on histopathological examination, similar to the epithelioid glioblastoma variant, but these tumors can be easily distinguished by immunohistochemistry for epithelial membrane antigen and glial fibrillary acidic protein (GFAP) [42, 43]. This evidence concerns the gene MUC1 and Rhabdoid Meningioma.
